Document Type and Number:
Japanese Patent JP2023173660
Kind Code:
A
Abstract:
To suppress the lowering of an injection speed of a cooling liquid even if a quantity of the cooling liquid injected into a compressor chamber is reduced.SOLUTION: A liquid cooling type rotating compressor comprises a compressor main body having a compression chamber formed of a fixed wall and a rotating wall for compressing a gas, and a liquid injection path for injecting a cooling liquid into the compression chamber, and adjusts a discharge flow rate by changing a rotational speed of the rotating wall. Also, the compressor comprises a liquid quantity adjustment part for adjusting a quantity of the cooling liquid supplied to the compressor main body from the liquid injection path according to a change of the rotational speed of the rotating wall, and a compressed gas supply path for supplying a compressed gas to a downstream side of the liquid quantity adjustment part in the liquid injection path, and supplies the compressed gas to the liquid injection path from the compressed gas supply path according to the quantity of the cooling liquid which is supplied to the compressor main body.SELECTED DRAWING: Figure 1
